An Analysis of Human-Generated Friendship Recommendations /slideshow/an-analysis-of-humangenerated-friendship-recommendations/69091993 ffproject-161116122624
Online social networks support users in a wide range of activities, such as sharing information and making recommendations. In this talk, I will talk about a human-generated recommendations of friendship based on hashtags that emerged in Twitter around 2010. I will present a study of a large-scale corpus of human friendship recommendations, using a large corpus of tweets gathered over a 24 week period and involving a set of nearly 6 million users. I will show that these explicit recommendations had a measurable effect on the process of link creation, increasing the chance of link creation between two and three times on average, compared with a recommendation-free scenario. Also, ties created after such recommendations have up to 6% more longevity than other Twitter ties. Finally, I will talk about a supervised system that ranks our user-generated recommendations, surfacing the most valuable ones with high precision (0.52 MAP). We find that features describing users and the relationships between them are discriminative for this task. After the talk, we will carry out some examples on the collection of online data ]]>

User behavior in online social media is not static, it evolves through the years. In Twitter, we have witnessed a maturation of its platform and its users due to endogenous and exogenous reasons. While the research using Twitter data has expanded rapidly, little work has studied the change/evolution in the Twitter ecosystem itself. In this pa- per, we use a taxonomy of the types of tweets posted by around 4M users during 10 weeks in 2011 and 2013. We classify users according to their tweeting behavior, and nd 5 clusters for which we can associate a different dominant tweeting type. Furthermore, we observe the evolution of users across groups between 2011 and 2013 and interesting insights such as the decrease in conversations and increase in URLs sharing. Our findings suggest that mature users evolve to adopt Twitter as a news media rather than a social network.]]>

Follow My Friends This Friday! An Analysis of Human-generated Friendship Recommendations /slideshow/presentation-29045321/29045321 presentation-131209125021-phpapp02
In Twitter, the hashtag #FF, or #FOLLOWFRIDAY, arose as a popular convention for users to create contact recommendations for others. Hitherto, there has not been any quantitative study of the effect of such human-generated recommendations. This paper is the first study of a large-scale corpus of human friendship recommendations based on such hashtags, using a large corpus of recommendations gathered over a 24 week period and involving a set of nearly 6 million users. We show that these explicit recommendations have a measurable effect on the process of link creation, increasing the chance of link creation between two and three times on average, compared with a recommendation-free scenario. Also, ties created after such recommendations have up to 6\% more longevity than other Twitter ties. Finally, we build a supervised system to rank user-generated recommendations, surfacing the most valuable ones with high precision ($0.52$ MAP), and we find that features describing users and the relationships between them, are discriminative for this task. ]]>

We show that these explicit recommendations have a measurable effect on the process of link creation, increasing the chance of link creation between two and three times on average, compared with a recommendation-free scenario. Also, ties created after such recommendations have up to 6\% more longevity than other Twitter ties. Finally, we build a supervised system to rank user-generated recommendations, surfacing the most valuable ones with high precision ($0.52$ MAP), and we find that features describing users and the relationships between them, are discriminative for this task. <img style="border:1px solid #C3E6D8;float:right;" alt="" src="https://cdn.slidesharecdn.com/ss_thumbnails/presentation-131209125021-phpapp02-thumbnail.jpg?width=120&amp;height=120&amp;fit=bounds" /><br> In Twitter, the hashtag #FF, or #FOLLOWFRIDAY, arose as a popular convention for users to create contact recommendations for others. Hitherto, there has not been any quantitative study of the effect of such human-generated recommendations. This paper is the first study of a large-scale corpus of human friendship recommendations based on such hashtags, using a large corpus of recommendations gathered over a 24 week period and involving a set of nearly 6 million users. We show that these explicit recommendations have a measurable effect on the process of link creation, increasing the chance of link creation between two and three times on average, compared with a recommendation-free scenario. Also, ties created after such recommendations have up to 6\% more longevity than other Twitter ties. Finally, we build a supervised system to rank user-generated recommendations, surfacing the most valuable ones with high precision ($0.52$ MAP), and we find that features describing users and the relationships between them, are discriminative for this task.
